20 + 50 + 20 + 10 = 50 = 150
4 + 2 + 10 + 50 = 66
10 + 10 + 10 + 10 + 10 = 50
30 + 10 + 5 + 5 = 50
x+10<50
190
10 plus 20 plus 30plus 40 plus 50 equals 150 because 50 plus 40 equals 90 plus 30 =120+20= 140 then + 10 = 150
18 + 10 + 20 + 30 + 15 + 50= 143

50 - 40 = 10 + 0
50 + 40 + 40 + 40 + 30 + 30 + 20 + 10 = 260
thinking is amazing
